HRV Heat Transfer

HRV Heat Transfer makes the most of your existing heat sources by spreading their warmth into other areas of your home. It uses heat from your fireplace or heat pump to balance the temperature throughout your home. Innovative centrifugal fans push air rather than blow it, for minimal noise and air disturbance. It’s easily installed onto your HRV core ventilation system and simple to operate with our new Touchscreen Keypad, utilising set & forget technology.

We brought a home with an HRV SYSTEM already installed, it was on all documentation, and visibley we could see that it was there. Not until it got cold and damp outside did we fully appreciate its power and the fact that the realestate agent had under valued it. We live in a large area, kitchen, lounge and hall all in one, if we leave all the bedroom doors open during the day the distribution of warmth from the HRV roof system is amazing. We got a bargain, the next people who purchase our house will know fully what they are buying and its value.

We had our HRV installed and have noticed a considerable difference overnight. The condensation that would be on the windows even on a slightly cool day has gone completely. Being in Ashburton we get some quite harsh frosts, and even then the windows are clear. It is such a great sign to open the curtains on these days and not have to wipe them down every day! The HRV has also warmed the 'base temperature' of our home and it is amazing how warm the roof space can be - even on the chilly days. We would highly recommend HRV to anyone.

Several years ago, in our 2 level home in Botany Downs, we experienced some difficulty in keeping it warm due to cold air coming up the stairs from the entrance to the main living area. We also had difficulty with condensation forming on the windows during the Winter. Then we discovered the HRV system and all the benefits it could offer. With our concrete tile roof, we learned that there was a big source of warm air accumulating in the roof space during the daytime that could be filtered, by way of a fan down into the living areas. This proved to be a very economical form of heating and at the same time, almost totally eliminated all the condensation from our windows. Then, in the Summer we discovered an additional bonus in the evenings and during the hot, humid nights. As soon as the temperature of the air in the roof space dropped below that of the air in the house, we had a supply of fresh cooling air being filtered through the house, making sleep so much more comfortable. We later added a heat pump to the equation and found that the 2 systems compliment each other beautifully. So when we moved house almost 3 years ago, one of the first things we did was to install an HRV System and a heat pump and we have been living in comfort ever since.

I own a mid 50's 3 bedroom house in Christchurch and had an HRV system installed mid way through last year. The difference to the internal atmosphere was immediate and as time progressed, the changes to the lives of my children and myself became more and more apparent. The biggest surprise was that during last winter, we only ran our heat pump 4 times! The house was dry thanks to the positive pressure atmosphere, the cold was kept out and the allergen levels in spring were almost non existant also thanks to the HRV system filtration, this is a big plus for us as well as we live in a high pollen area. Am I happy with my option to go with an HRV system, very much yes. Thanks, HRV.


My husband and I installed a HRV system after a really terrible winter with our 3 year old son, who was diagnosed with a brain disorder at birth. (Lissencephaly). The main issue we have is respiratory illness as we've lost count how many times he's had pneumonia and come close to losing him because of it. Within a week of the HRV being installed we seen big changes the air felt dryer and warmer instantly! It also definatley put a dent in the number of hospital visits we were making to Waikato Hospital. So Thankyou HRV, for keeping our family together.

  • HRV’s Heat Transfer system is designed to balance temperatures in the home in the most efficient way possible
  • It does this by taking advantage of existing heat sources and making them work harder.
  • Whilst one room in particular may be heated comfortably, other rooms in your home might be colder than you’d like.
  • The HRV Heat Transfer system uses a large fan and insulated ducting system to take the latent heat from a primary heat source and pushes it to other areas of the house that require a change in temperature.
  • The HRV Heat Transfer system is fully integrated with our core ventilation system so you can intelligently manage your invironment.
  • The result is a much more efficient use of your heating and a balanced, purer invironment overall.
